Application filed September 12,1930. ,Seriallfi'o. F 1

My invention relates to ventilators such as i are used in factories or large buildings, and

- may be easily operated irrespective of the has for its object to provide a multiple seal ing means forpreventing the ingress of rain, sleet, snow, dirt orother'objectionable mat ter when the ventilator isclosed, to prevent rattling, and to-offer a construction such as nature of the roof :of the building.

This invention is a ventilatingstructure q and has nothlng whatever to do with the roof except that the latter affords a means of support, and,j as it is advisable to show the ventilator as applied toa building,I have elected to show my improvement mounted on a skylight structure which latter 18 so well known thatit will bereferred to as anordinary roof structureelement.

Referring to the accompanyingdrawings, 'Figure 1 1s aside elevation showing my invention mounted on a skylight structure the latter being brokenaway. V

Figure 2 is a section at the.line'2-2 of Figure 1, showing the ventilator closed, and Figure 3 is a view similar to Figure 2 with the ventilator open.

Similar numerals of reference will be used to denote like parts in the several figures of the drawings.

The superstructure of the ventilator-com prises a plurality of spaced generally diverging frame supports 1,, preferably integral with a roof portion 2, and the lower ends of these supports are secured inanysuitable manner asby bolts 3 to apart of thereof structure of the building, in the present ina stance to angle bars 4 whichlatter support the skylight or other roof portioni5 of the building. I I v I The; roof portionst rest'upo'n the ends of cross-struts-(l (only one shown) the latter I manner to said struts, as by bolts? 45 affording a bracefor the supports 1, and these portions at are secured in any suitable Bolted to the roof portion 2 is a metal sheet 8, and spaced guides 9 are bolted at the top and bottom respectively to the parts 2 and 6, and a hanger 10 is also bolted to the part 2 within which hanger a pulley 11' is journaled. it

12 i an elongated'metaltbar within the spacebetween the guides 9, andponnected' to this-barges by a iing*l8,;is a rope or cable 14. which isipassed'up; over the pulleyl'l. and thence downwardly, so as to'be convenient of access. I I s 15 areear-s secured'jto the bar '12 at suitable intervals, '16 are the ventilator closures p ivotallly swung theirnpp'er ends at 717 from the side "edges ofth'e sheet 8, and, to the inner faces .of t11e e.,c10sures '16 are jbolted s I cross-struts'-'6-and guides 9,*fconstitute one" unit .of t lierventilatorconstruction, and there are as; many of ,these units "as desirable and they are spaced-apart,,-and'1t 1s between these unitsthat theair passes for jathe purposesof ventilationfbut the-drawings show but one of these units, since further illustration in'this,respect-would be mere;cl-uplieation.-

' 'But the-sheet 8, the closureslfi, anglebars or roof supports l, roof portions smut,

opening, although in very long; openings,

12, all extendthe full length-of the ventilator is sometimes advisable to jsubdivitlethe 'ven- 9 tilatingclosures and operate, them as in'de,

pendent sections, and in cases "like "this the changes that would be nade' arequiteobvious.

V Se'cured to the lower outer portions of the frames .1 are sheet metal strips'20 which ex;

;ten dthe fullileng'th of the ventilator opening and areresilient, the upper edgesbeing,

formed into seats. 21 whilejthe lower edges- 1 'e'lxte'nd' along thereof portions 5 ;and are, in

close contact therewith 3st to ings 22'.

:1 he closures, 16,,when no, ventilatipnliis l desired, forced tightly-{against the seats .1 by "the weight of the bar. 12, and as'these seats are resilient the sealing of thispoint' is, efficient. i But-the lower ends ofthe closures are bent inwardly andoutwardly' so to -form anv gular parts-23 are close, proximity to the metal strips 20, so that, if the seats 21 are stressed unduly the parts 23 will seat against the strips 20, and the lower extremities 24 will seat against the fiashings 22, thus afi'ording multiple sealings for the closures. I desire to particularly lay stress on the V "fact that my invention has nothing whatever to do with any particular kind of roof to a building, it being merely necessary, of course, that the building should have the usual ventilating opening over which my improved ventilator is mounted as hereinbefore described, and that pairs of frame supports 1 are spaced apart throughout the length of this opening. I The metal roof portion 8, the metal sealing strips 20, the bar 12 and the closures 16 all extending the full length of said opening, and there can be as many connections for elevating this bar as desired, and it is further to be noted that the bar may be pushed upward by any ordinary means applied from below, it being merely necessary that the hair should be freely suspended when the ventilator is closed so as to exert a constant force to insure the resilient sealing contacts of the closures with the seating portions carried by the strip 20, in the manner herein: before described.

It is not necessary that a special roof 8 be provided, since the top portion 2 of the frames 1 may extend the length of the ventilator :(pening and the side frames themselves boltthereto or even made integral therewith, and, as far as the pivotal points 17 are concerned, these may be provided by bolting suitable eyes to the top of the frame structure or by soforming the latter as to readily afford pivotal connections for the closures, this being a matter fully within thescope of ordinary mechanical judgment, but the struc-' ture shown in the drawings is preferred, since it is water and dirt proof.

What is claimed is 7 1. In a ventilating structure for roofs having ventilating openings, of spaced frames secured to the sides of said opening, having a roof portion rigid with the tops thereof and extending the length of said opening, multiple resilient sealing seats secured to said frames and extending the length closures so as to stress the sealing contacts between the closures and superstructure.

In testimony whereof I aflix my signature hereto.

of said opening, ventilator closures pivotally swung at their upper edges byintercurling the edge of the roof portion and the closure and carrying multiple sealing parts for contacting with the seats when the ventilator is closed, and means for operating said closures.

sealing seats carriedby the. lower side edges of said superstructure, ventilator closures swung from the edge of the roof portion by lllj
